Technically none, as the jeopardy screen is a screen of answers. The players of the game provide the question to that answer. This is why all responses must be phrased as a question or points are not awarded.
Another answer: The first round of Jeopardy has six categories, with five clues in each category. Therefore, there are 30 clues, each of which must be responded to in the form of a question.
There are 3 of the Daily Doubles per game, 1 in the first round, and 2 in the second round. The Double Jeopardy is the name of the second round of Jeopardy, which has the same size of six categories with five questions or clues (30) that the first round does. It's just that the point values are doubled in the double Jeopardy round.
five questions in each of the six categories for each round
6 categories with 5 questions in both the Jeopardy and Double Jeopardy round total 60 Squares
There are 1 in the first round 2 of them in the second Double Jeopardy round and you could call final jeopardy the 4th since you can double your money if you bet it all, but is is not called a daily double so the answer is 3
4 or 5

You can pick some of the characters in the book that you can also find 5 questions to ask and make them categories for your Jeopardy board. You might ask questions about the author in another category. Locations and events in the book can also be used as categories. Jeopardy uses facts to ask a question that lead to the answer.
